1. Pan Am was the first airline to operate the TriStar 500 with extended wingtips/active ailerons, in 1980?2. The first TriStar 500 models delivered to British Airways in 1979 did not originally have the wingtip extensions? They were retrofitted later.

3. The extended wingtips/ active ailerons were first installed and tested in the L-1011 prototype (N1011)?
